The way I see it, if you are doing what your scriptures tell you to do, you are a ___ian/___ist, plain and simple. If you honestly believe that your deity exists and you love and obey them, you will do their bidding no questions asked. If you feel that there is something questionable in their instructions you're probably not taking that deity seriously and if you're not convinced that you will be punished for disobeying them you might want to question your beliefs. One idea you might explore is that you might not be doing their will but yours instead.
The fact that the Bible and other texts were rewritten and there are many sects in every religion should raise a red flag to someone that they might not be following the Right Path of their deity but be following the path of some earthly leader. They can't be all right and there isn't any evidence one is more legitimate than the other, unless you accept what doesn't conflict with your own beliefs and desires. That being the case, you are not a follower of your deity, you are just catering to your own whims.
